FIELD OF TECHNOLOGY

The present technology relates to assembling various vehicles of a family of vehicles by connecting multiple frame modules, and to side-by-side off-road vehicles having a storage compartment.

BACKGROUND

Side-by-side off-road vehicles are typically used in off-road conditions. Different models of side-by-side off-road vehicles are designed to offer different features for particular applications. For instance, in some cases, some vehicles are provided with additional seating for accommodating more passengers in the vehicle. In other cases, additional space for transporting cargo is prioritized by equipping the vehicle with additional cargo holding space in the form of a larger cargo bed disposed behind a cockpit of the vehicle.

While it is desirable for a given manufacturer to offer different models of side-by-side off-road vehicles with different features, the variations in the vehicle models can complicate their design and/or assembly. Notably, the frames of the various off-road vehicle models offered by a manufacturer are typically substantially different in order to accommodate particular features (e.g., additional seating or cargo space). Consequently, the manufacturer will typically have a significant amount of different frame components on hand to be able to manufacture the different vehicle models. Moreover, if the variations in the frames of the vehicles are important enough, the vehicles' frames may require complete redesigns to ensure that each vehicle frame can properly support the loads exerted thereon by the components mounted on the frame.

Furthermore, although the addition of a cargo bed substantially increases the cargo carrying capacity of side-by-side off-road vehicles, users may not want to put all of their cargo in the cargo bed. The cargo bed is typically pivotable to permit easy dumping of its content, such a soil for example. As such, should a user carry other things in the cargo bed in addition to the cargo that is to be dumped, the user has to remove these other things before dumping the cargo that is to be dumped in order to prevent these other things from being dumped at the same time. Once this cargo is dumped, the user as to put these other things back in the cargo bed. This is inconvenient to the user. As such it would be desirable to provide other locations in the vehicle to store items. However, due to the compact nature of side-by-side off-road vehicles, the cockpit, the power pack (i.e. engine, transmission and associated components), the air intake system, the exhaust system, the fuel tank and the cargo bed occupy most of the space in the vehicle. Some side-by-side off-road vehicles are provided with storage compartments in the cockpit, such as a glove box for example, but these are relatively small, thus only permitting the storage of small items.

In addition, the cargo bed is typically not covered. As such, anything stored in it is exposed to the elements, which may not be desirable for some cargo. Although a tarpaulin can be used to cover the cargo stored in the cargo bed, this can be inconvenient to the user.

There is therefore a desire for a method for assembling multiple vehicles of a family of vehicles having different functional characteristics, as well as for a side-by-side off-road vehicle having storage capacity in addition to the storage capacity provided by a cargo bed to address at least in part some of the aforementioned drawbacks.

DETAILED DESCRIPTION

The present technology will be described with respect to a family of side-by-side off-road vehicles, including vehicles 10, 510, 610. While the illustrated side-by-side off-road vehicles 10, 510, 610 are equipped with wheels, it is contemplated that the present technology could be applied to side-by-side off road vehicles having two or more of the wheels replaced by other types of ground engaging members (e.g., skis or track assemblies).

The vehicle 10 will be described with reference to FIGS. 1 and 2. The vehicle 10 has left and right front wheels 12 and left and right rear wheels 14. As shown in FIG. 2, the vehicle 10 has a wheelbase length WB_(A) measured longitudinally between the center 13 of the front wheels 12 and the center 15 of the rear wheels 14 (when the wheels 12, 14 are in a straight ahead orientation—i.e., not turning). The front and rear wheels 12, 14 are connected to a frame 16 of the vehicle 10 by front and rear suspension assemblies 18, 20 respectively. In the present embodiment, the front and rear suspension assemblies 18, 20 are of the types described in United States Patent Publication No. US 2017/0174027 A1, published Jun. 22, 2017, the entirety of which is incorporated herein by reference. It is contemplated that other types of suspensions assemblies could be used. As will be described in more detail below, the frame 16 includes two frame modules 250, 350 connected to one another to form part of the frame 16.

The vehicle 10 has a cockpit 22 inside which a driver seat 24, and two passenger seats 25, 26 are provided side-by-side such that the seats 24, 25, 26 form a “seat row” FSR. The passenger seat 25 is provided between the seats 24, 26. In the present embodiment, the driver seat 24 is on the left side of the vehicle 10 and the passenger seat 26 is on the right side of the vehicle 10, but it is contemplated that it could be the opposite. It is contemplated that the passenger seat 25 could be omitted. It is also contemplated that the individual driver and passenger seats 24, 25, 26 could be replaced by a bench seat spanning a majority of the width of the cockpit 22 which would define the driver and the passenger seats. Furthermore, the seats 24, 25, 26 could be any suitable type of seats (e.g., bucket seats).

A steering wheel 27 is disposed in front of the driver seat 24. The steering wheel 27 is operatively connected to the two front wheels 12 for steering the vehicle 10.

As will be described in greater detail below, a roll cage 28 is provided over the cockpit 22 and is connected to the frame 16. The roll cage 28 installed on the vehicle 10 is chosen amongst a family of roll cages in accordance with a size of the cockpit 22 of the vehicle 10. As will be described further below, the vehicles 510, 710 may have different roll cages installed thereon.

The driver and passenger enter and exit the vehicle 10 from the sides thereof. Flexible lateral covers 30 are selectively provided across the opened sides of the cockpit 22. In an alternative embodiment shown in FIGS. 20 and 21, the flexible lateral covers 30 have been replaced by full doors 32. It is contemplated that instead of the full doors 32, the vehicle 10 could be provided with door panels that do not have windows. It is also contemplated that the vehicle 10 could not be provided with flexible lateral covers 30, doors 32 or door panels.

The vehicle 10 has a storage compartment 50 disposed rearward of the cockpit 22. The storage compartment 50 has left and right access apertures 52 (FIG. 2) defined in the left and right sides of the vehicle 10 respectively for providing access to the storage compartment 50. The access apertures 52 are selectively closed by doors 54, a left one of which is shown in FIG. 1. In the present embodiment, the left and right doors 54 are removable. It is contemplated that the doors 54 could be hinged to the frame 16 so as to pivot between opened and closed positions. It is contemplated that the doors 54 could be pivotable and removable. It is also contemplated that the doors 54 could be provided with key locks, or other types of locks, in order to prevent unauthorized access to the storage compartment 50. It is also contemplated that the doors 54 could be replaced by flexible lateral covers such as nets. The storage compartment 50 is disposed rearward of the front wheels 12 and forward of the rear wheels 14 such that the wheels 12, 14 do not interfere with the access apertures 52 and the removal of the doors 54. The storage compartment 50 will be described in more detail below.

A motor compartment 60 is disposed rearward of the storage compartment 50. As best seen in FIGS. 3 to 6, a motor 62 is disposed in and supported by the motor compartment 60. In the present embodiment, the motor 62 is an internal combustion engine, but other types of motors, such as an electric motor, are contemplated. A continuously variable transmission (CVT) 64 (shown in dotted lines in FIG. 5A) is provided in the motor compartment 60 on a left side of the motor 62. A CVT housing 66 houses the CVT 64. The CVT 64 operatively connects the motor 62 to a transaxle 68 (FIG. 5A) to transmit torque from the motor 62 to the transaxle 68. The transaxle 68 is operatively connected by half-shafts (not shown) to the two rear wheels 14 to drive the two rear wheels 14. As shown in FIG. 5B, the transaxle 68 has a transaxle output axis 69 about which the half-shafts connected thereto rotate. Driveshaft (not shown) operatively connect the transaxle 68 to a front differential 65 (FIG. 5B). The front differential 65 is operatively connected by half-shafts (not shown) to the two front wheels 12 to drive the two front wheels 12. As shown in FIG. 5B, the front differential 65 has a front differential output axis 67 about which the half-shafts connected thereto rotate. The vehicle 10 has a front-rear output distance FR_(A) measured longitudinally between the front differential output axis 67 and the transaxle output axis 69 (i.e., the distance between the frontmost output axis and the rearmost output axis). It is contemplated that the transaxle 68 could be replaced by a transmission and differential that are separate from each other. It is contemplated that the CVT 64 could be replaced by an automatic or manual geared transmission or another type of transmission. It is contemplated that only the two front wheels 12 or the two rear wheels 14 could be driven by the motor 62 or that the vehicle 10 could selectively switch between driving two of the wheels 12, 14 and driving all four wheels 14. A muffler 70 is disposed in the motor compartment 60 rearward of the motor 62. The muffler 70 is fluidly connected to exhaust ports of the motor 62 to receive exhaust gas therefrom. A fuel tank 72 is provided in the motor compartment 60 on a right side of the motor 62. It is contemplated that the fuel tank 72 could be provided on the left side of the motor 62 and that the CVT 64 could be provided on the right side of the motor 62.

As can be seen in FIGS. 3 and 4, an engine air intake conduit 74 is provided to supply air to the motor 62. The engine air intake conduit 74 includes an inlet 76, an air box 78 and a pipe 80. The inlet 76 and the air box 78 are disposed on a right side of the vehicle 10, rearward of the passenger seat 26, above the storage compartment 50. The air intake aperture defined by the inlet 76 faces rightward. The inlet 76 is connected to the air box 78 which contains an air filter (not shown). The air box 78 is connected to the pipe 80. From the air box 78, the pipe 80 extends leftward and downward, and then has a section 82 that extends horizontally and longitudinally rearward above the storage compartment 50. The pipe 80 is connected to a throttle body, which is connected to an air intake manifold, which is connected to the air intake port of the motor 62.

As can also be seen in FIGS. 3 and 4, a coolant bottle 84 disposed to the left of the air box 78, rearward of the passenger seat 25, above the storage compartment 50. A coolant line 86 communicates the coolant bottle 84 with the motor 62 to permit the flow of coolant therebetween.

As can also be seen in FIGS. 3 and 4, a CVT air intake conduit 88 is provided to supply air inside the CVT housing 66 to cool the CVT 64. The CVT air intake conduit 88 includes an inlet 90, pipes forming a gooseneck 92 and a pipe 94. The inlet 90 and the gooseneck 92 are disposed on a left side of the vehicle 10, rearward of the driver seat 24, above the storage compartment 50. The air intake aperture defined by the inlet 90 faces leftward. The inlet 90 is connected to the gooseneck 92 which is connected to the pipe 94. The pipe 94 has a section 96 that extends horizontally and longitudinally rearward above the storage compartment 50. The pipe 94 is connected to the CVT housing 66.

With reference to FIGS. 1, 2, 5A, 5B and 6, the vehicle 10 has a cargo bed. The cargo bed of the vehicle 10 is chosen from a group of cargo beds designed to fit one or another of the vehicles 10, 510, 710. Notably, the group of cargo beds includes cargo beds of two sizes: a long cargo bed 100 and a short cargo bed 300. The long cargo bed 100 has a length L_(L) (FIG. 20) that is greater than a length L_(S) of the short cargo bed (see FIG. 25). The vehicle 10 is equipped with the long cargo bed 100.

The cargo bed 100 has a floor 102, a front wall 104, left and right side walls 106 and a tailgate 108. It is contemplated that one or more of the front wall 104, the left and right side walls 106 and the tailgate 108 could be selectively removable. It is also contemplated that one or more of the front wall 104, the left and right side walls 106 and the tailgate 108 could be omitted. It is also contemplated that the tailgate 108 could be replaced by a rear wall, which could be selectively removable. It is also contemplated that the cargo bed 100 could have a movable or removable top. Brackets 110 are connected to the bottom of the cargo bed 100 near a rear thereof and pivotally connect the cargo bed 100 to the rear of the frame 16, as will be described in greater detail below. As such, the cargo bed 100 can pivot between a lowered position shown in FIGS. 1, 2 and 5 and a raised position shown in FIG. 6. As best seen in FIG. 5, the cargo bed 100 is sufficiently long such that, when the cargo bed 100 is in the lowered position, it extends over the motor compartment 60 and the storage compartment 50. In the present embodiment, the length L_(L) of the cargo bed 100 (i.e. the horizontal distance from its front-most point to its rearmost point with reference to FIG. 20) is greater than the distance D measured from the front-most point of the vehicle 10 to the front-most point of the cargo bed 100 (i.e. the horizontal distance with reference to FIG. 20) when the cargo bed 100 is in the lowered position. It is contemplated that when the cargo bed 100 is in the lowered position, it could extend over only a portion of the motor compartment 60 and/or a portion of the storage compartment 50. With reference to FIG. 6, a lock 112 is connected to the bottom of the cargo bed 100 near a front thereof. The lock 112 includes a pair of spring-biased hooks 114 and a release handle 116. When the cargo bed 100 is pivoted down in the lowered position, each hook 114 engages a laterally-extending frame member 118 (FIGS. 5C, 14) of the frame 16, thus locking the cargo bed 100 in the lowered position. In the lowered position of the cargo bed 100, the lock 112 is above the storage compartment 50. To pivot the cargo bed 100 to the raised position, a user first actuates the release handle 116 thereby causing the hook 114 to release the frame member 118. The cargo bed 100 can then be pivoted to the raised position. A gas cylinder 120 (FIG. 6) connected between the frame 16 and the bottom of the cargo bed 100 helps to maintain the cargo bed 100 in the raised position. In the present embodiment, the cargo bed 100 is pivoted manually between its lowered and raised positions, but it is contemplated that it could be pivoted by an actuator such as an electric or hydraulic actuator.

While the lengths L_(L), L_(S) are shown as being measured from respective outer surfaces of the cargo beds 100, 300 (in the case of the long cargo bed 100, from the outside of the front wall 104 to the outside of the tailgate 108), it is to be understood that for each of the lengths L_(L), L_(S), there is an associated inner length of each of the cargo beds 100, 300. Thus, the lengths L_(L), L_(S) may alternatively refer to the inner lengths of the cargo beds 100, 300 (in the case of the long cargo bed 100, from the inside of the front wall 104 to the inside of the tailgate 108).

Turning now to FIGS. 7 to 15, the frame 16 will be described in more detail. In this embodiment, the frame 16 includes two frame modules 250, 350 connected to one another to form part of the frame 16. Notably, the frame 16 includes a front frame module 250 and a rear frame module 350 connected to and disposed rearwardly of the front frame module 250. The front and rear frame modules 250, 350 will be described in greater detail below.

FIGS. 7 to 9 show the front frame module 250 of the frame 16. As shown in FIG. 8, the front frame module 250 has a first section 130 and a second section 132 disposed rearward of the first section 130. The first section 130 of the front frame module 250 defines part of the cockpit 22. In the present embodiment, some components of the frame 16 are part of both sections 130, 132 of the front frame module 250. For example, the frame 16 has a tunnel 136 that extends along the bottom of the first and second sections 130, 132. The driveshaft (not shown) connecting the transaxle 68 to the front differential 65 extend inside the tunnel 136.

The front frame module 250 has a lower frame structure 252 which supports a floor 218 (FIG. 15). The lower frame structure 252 extends across both sections 130, 132 of the front frame module 250. The lower frame structure 252 includes a plurality of horizontal members, including two parallel longitudinally-extending frame members 254 defining the lateral ends of the lower frame structure 252, two central longitudinally-extending frame members 255 parallel to the longitudinally-extending frame members 254 (and disposed laterally between the frame members 254), and laterally-extending frame members 256 that interconnect the longitudinally-extending frame members 254 to the longitudinally-extending frame members 255. The tunnel 136 is formed by the longitudinally-extending frame members 255 and a top tunnel cover 137 connected to the two longitudinally-extending frame members 255. The laterally-extending frame members 256 connect the longitudinally-extending frame members 254 to the tunnel 136. Connecting members 257 (one of which is shown in FIG. 7) extend laterally and are connected between the longitudinally-extending frame members 255.

The front frame module 250 also has two rearwardly and vertically extending frame members 142 and two rearwardly and vertically extending frame members 144 connected to the lower frame structure 252. The frame members 144 are disposed rearward of the frame members 142 and therefore the frame members 142, 144 will be referred to as front vertically-extending frame members 142 and rear vertically-extending frame members 144 respectively. The front and rear vertically-extending frame members 142, 144 extend vertically from the longitudinally-extending frame members 254 of the lower frame structure 252. Notably, one of each of the front and rear vertically-extending frame members 142, 144 is connected to a corresponding one of the longitudinally-extending frame members 254. A laterally-extending frame member 258 interconnects the front vertically-extending frame members 142 at a position vertically higher than the lower frame structure 252. In addition, as the front vertically-extending frame members 142 are inclined at an angle, a vertical support 259 is connected between each of the front vertically-extending frame members 142 and a corresponding one of the longitudinally-extending frame members 254. As will be described in greater detail below, when the frame 16 is assembled, the rear vertically-extending frame members 144 are connected to the rear frame module 350.

At a front portion thereof, the front frame module 250 has left and right frontwardly and vertically extending frame members 260 which are interconnected at their top ends by a laterally-extending upper frame member 262. The laterally-extending upper frame member 262 generally defines a front end of the cockpit 22 of the vehicle 10. The front frame module 250 also has a front suspension mounting structure 264 disposed forward of the cockpit 22 for connecting the front suspension assemblies 18 to the frame 16. The front suspension mounting structure 264 is a portion of the front frame module 250 that has the smallest width for accommodating the front wheels 12. The front suspension mounting structure 264 includes two generally inverted Y-shaped members 266, each of which is connected to a corresponding central longitudinally-extending frame member 255 forwardly of the top tunnel cover 137. At their top ends, the inverted Y-shaped members 266 are also connected to the laterally-extending upper frame member 262.

Between the front vertically-extending frame members 142 and the frontwardly and vertically extending frame members 260, the front frame module 250 defines a seat row space 265 of the cockpit 22 adapted for accommodating the seat row FSR of the vehicle 10. That is, the seat row FSR is installed in the seat row space 265.

At its frontmost end, the front frame module 250 has a bumper structure 270 which is connected to the central longitudinally-extending frame members 255 at a lower end, and to the laterally-extending upper frame member 262 at an upper end via connecting members 271 which extend downwardly and frontwardly from the laterally-extending upper frame member 262.

The roll cage 28 is connected to the first section 130 of the front frame module 250 to extend over the seat row FSR. The roll cage 28 has front left and right legs 138 and rear left and right legs 140. The front legs 138 are connected to the first section 130 at a front of the cockpit 22 to left and right roll cage mounts 139 defined at the ends of the laterally-extending upper frame member 262. Each front leg 138 has a first portion that extends upwardly and rearwardly from the bottom end of the front leg 138, an elbow formed at a top end of the first portion, and a second portion that extends rearwardly from the elbow to an upper end of the front leg 138. As such, the front legs 138 form top left and top right sides of the roll cage 28. The rear legs 140 are connected to the first section 130 at a rear of the cockpit 22, in particular to left and right roll cage mounts 143 defined at the top ends of the front vertically-extending frame members 142 (located longitudinally rearward of the roll cage mounts 139). The roll cage mounts 143 include a plurality of openings extending laterally across the front vertically-extending frame members 142. A front upper lateral member 145 interconnects the front legs 138 at a top portion thereof. A rear upper lateral member 155 interconnects the rear legs 140 to one another at a top portion thereof. Rear lower lateral members 157 interconnect the rear legs 140 to one another at a lower portion thereof. A shoulderbar 159 is connected to each of the rear legs 140. The front and rear legs 138, 140 are connected to one another via two connectors 149. Notably, each connector 149 is connected to one of each of the front and rear legs 138, 140.

As will be described in greater detail below, the rear vertically-extending frame members 144 define mounts 147 (FIGS. 7, 8) at their top ends for mounting a different one of the roll cages. The mounts 147 are located longitudinally rearward of the roll cage mounts 143 and are configured similarly to the roll cage mounts 143.

The second section 132 of the front frame module 350 defines in part a configurable space 275. More specifically, the configurable space 275 is defined in part between the front vertically-extending frame members 142, the rear vertically-extending frame members 144 and the lower frame structure 252. As such, the configurable space 275 is disposed rearward of the front seat row space 265. As will be seen below, the frame 16 can be selectively adapted to use the configurable space 275 to different ends.

FIGS. 10 to 12 show the rear frame module 350 of the frame 16. The rear frame module 350 defines part of the motor compartment 60 for supporting the motor 62. The rear frame module 350 has a front end 351 and a rear end 353. A width of the rear frame module 350 decreases from the front end 351 to the rear end 353. The rear frame module 350 has left and right lower longitudinally-extending frame members 352 and left and right upper longitudinally-extending frame members 354, each of which extends horizontally at an angle to the longitudinal direction. As shown in FIGS. 10 and 11, the rear frame module 350 has left and right laterally-extending retaining members 355 which are connected to and, in this embodiment, extend through respective ones of the longitudinally-extending frame members 354. A portion of each of the retaining members 355 extends laterally inwardly from and is supported by a respective longitudinally-extending frame member 354. As shown in FIG. 11, each of the longitudinally-extending frame members 354 forms an angle θ relative to a corresponding laterally-extending retaining member 355. In this embodiment, the angle θ is approximately equal to 120°. Moreover, in this embodiment, a distance between the inner ends of the retaining members 355 is approximately equal to a distance between the hooks 114 of the cargo bed 100. As will be explained in greater detail below, in the vehicles 510, 710, the retaining members 355 are used for engaging the hooks 114, 314 of a lock 112, 312 connected to a corresponding cargo bed such as to retain the cargo bed in place in its lowered position. As such, the retaining members 355 and the longitudinally-extending frame members 354 can be referred to as a lock-engaging frame subassembly 357 which supports and engages the lock 112, 312. The longitudinally-extending frame members 352, 354 are interconnected at their front ends by left and right vertical members 358. Parallel lower and upper laterally-extending frame member 356, 360 extend between and connect the vertical members 358 at the front end 351 of the rear frame module 350. The upper laterally-extending frame member 360 is configured to engage a recess 148 (FIGS. 7, 8) defined in each of the rear vertically-extending frame members 144 of the front frame module 350. A rear laterally-extending frame member 364 connects the upper longitudinally-extending frame members 354 to one another at their rear ends.

The rear frame module 350 also has a rear suspension mounting structure 362 for connecting the rear suspension assemblies 20 to the frame 16. The rear suspension mounting structure 362 includes two inverted Y-shaped mounts 376 disposed laterally opposite from one another. The inverted Y-shaped mounts 376 are connected at a lower end thereof to the lower longitudinally-extending members 352 (via connecting members 363) and, at an upper end thereof, to the upper longitudinally-extending members 354. A bottom mounting plate 372 extends between the inverted Y-shaped mounts 376 and a pair of upper mounting flanges 374 extend inwardly form the inverted Y-shaped mounts 376 for connecting other components (e.g., the transaxle 68, the muffler 70, etc.) to the rear frame module 350.

The motor 62, the transaxle 68, the muffler 70 and the fuel tank 72 are connected to the rear frame module 350 of the frame 16. The motor 62, the CVT 64, the CVT housing 66, the transaxle 68, the muffler 70 and the fuel tank 72 are disposed, at least in part, rearward of the rear vertically-extending frame members 144.

At its top portion, the rear frame module 350 has a cargo bed support structure 368 for supporting the cargo bed 100. More specifically, the cargo bed support structure 368 includes left and right corner members 369 connected to the ends of the rear laterally-extending frame member 364. Each of the corner members 369 has an axle 370 extending laterally outwardly therefrom. The axles 370 are coaxial with one another. Together, the axles 370 define in part a cargo bed pivot 371 for pivotably mounting the cargo bed 100 to the rear frame module 350. As such, the cargo bed 100 is pivotable about a cargo bed pivot axis 380 (FIGS. 11, 12) defined by the cargo bed pivot 371. More specifically, the brackets 110 connected to the bottom of the cargo bed 100 are pivotally connected to the cargo bed pivot 371 to allow the cargo bed 100 to pivot about the cargo bed pivot axis 380. As shown in FIG. 2, the vehicle 10 has a longitudinal cargo pivot distance PV_(A) measured between the center 13 of the front wheels 12 and the cargo bed pivot axis 380 (when the front wheels 12 are in a straight ahead orientation—i.e., not turning).

Once the front and rear frame modules 250, 350 are connected to one another, another structure of the frame 16 is connected to the font frame module 250 in accordance with a desired use of the configurable space 275. In this example, the vehicle 10 uses the configurable space 275 as the storage compartment 50 to store cargo therein as described above. Thus, in this embodiment, a storage compartment structure 150 is installed on the front frame module 250 such that the configurable space 275 defines at least in part the storage compartment 50 extending rearwardly of the seat row FSR. As such, in this embodiment, the second section 132 of the front frame module 250 defines in part the storage compartment 50.

As can be seen in FIG. 13, the storage compartment structure 150 has a front side 151 and a rear side 153. The storage compartment structure 150 comprises left and right longitudinally-extending frame members 152 and laterally-extending frame members 118, 154 connected between the longitudinally-extending frame members 152. The frame member 118 is disposed forwardly of the frame member 154. Frame members 156 extend diagonally and are connected to the laterally-extending frame members 118, 154 as well as to respective front ends of the longitudinally-extending frame members 152 and thus support the laterally-extending frame members 118, 154. More specifically, each of the diagonal frame members 156 extends inwardly from a front end of a corresponding one of the longitudinally-extending frame members 152 to the laterally-extending frame member 154. A middle portion of each diagonal frame member 156, between the ends thereof, is connected to and supports the laterally-extending frame member 118. As the laterally-extending frame member 118 is engaged by the lock 112 when the cargo bed 100 is in the lowered position, the laterally-extending frame member 118 and the diagonal members 156 can be referred to as a lock-engaging frame subassembly 119 which supports and engages the lock 112. Each of the diagonal frame members 156 forms an angle α relative to the laterally-extending frame member 118. As will be explained in greater detail below, the angle α is approximately the same as the angle θ defined between the longitudinally-extending frame members 354 and the laterally-extending retaining members 355 of the rear frame module 350. Thus, in this embodiment, the angle α is approximately equal to 120°. On the front side 151, connecting flanges 128 are provided at the front ends of the longitudinally-extending frame members 152. On the rear side 153, connecting brackets 125 are provided at the rear ends of the longitudinally-extending frame members 152. The connecting flanges 128 are configured to be connected to corresponding flanges 146 provided at the upper ends of the front vertically-extending frame members 142 of the front frame module 250. Notably, fasteners 158 (FIG. 14) are used to fasten the connecting flanges 128 to the flanges 146 of the front vertically-extending frame members 142. The connecting brackets 125 are configured to be connected to the mounts 147 defined at the top ends of the rear vertically-extending frame members 144. More specifically, each connecting bracket 125 defines a recess 127 for inserting therein an upper portion, including the mount 147, of a corresponding one of the rear vertically-extending frame members 144 such that the rear vertically-extending frame member 144 is straddled by the connecting bracket 125 (see FIGS. 14, 15). Fasteners are then inserted through openings provided in the connecting bracket 125 and corresponding openings defined by the mount 147.

The assembled frame 16 of the vehicle 10 is shown in FIGS. 14 and 15. As can be seen, the storage compartment structure 150 is connected between the front and rear vertically-extending fame members 142, 144 and extends over the configurable space 275. As such, the configurable space 275 defines in part a top of the storage compartment 50. As shown in FIG. 5, when the cargo bed 100 is in its lowered position, the cargo bed 100 extends over the storage compartment structure 150 (and thus over the configurable space 275). The front of each longitudinally-extending frame member 152 is fastened by the fasteners 158 to its corresponding frame member 142 which, as can be seen in FIG. 14, are vertically lower than fasteners 160 used to fasten the rear legs 140 of the roll cage 28 to the front vertically-extending frame members 142. Given their positions relative to the assembled frame 16, the longitudinally-extending frame members 152 may alternatively be referred to as upper left and right central frame members.

As can be seen from the assembled frame 16 of the vehicle 10 in FIGS. 14 and 15, in this embodiment, the first and second sections 130, 132 of the front frame module 250 respectively form a front frame section and a central frame section of the frame 16 and may thus be referred to as such. Meanwhile, as shown in FIG. 14, the rear frame module 350 forms a third section 134 of the frame 16 disposed rearward of the sections 130, 132 and which may thus be referred to as a rear frame section of the frame 16.

Furthermore, as shown in FIGS. 3, 4 and 6, the inlet 76 of the engine air intake conduit 74 and the inlet 90 of the CVT air intake conduit 88 are located rearward of the cockpit 22 and frontward of the rear frame module 350.

As mentioned above, besides allowing storage of cargo within the storage compartment 50, due to its relatively low height (i.e., approximately equal to a height of the rear frame module 350), the storage compartment structure 150 also allows equipping the vehicle 10 with the long cargo bed 100 (rather than the short cargo bed 300) which extends above the storage compartment structure 150 in the lowered position. Notably, in the lowered position, the long cargo bed 100 extends forwardly of the mounts 147 defined by the rear vertically-extending frame members 144. Thus, the storage compartment structure 150 may alternatively be referred to as a “cargo bed support structure extension” in that it extends the structure of the frame 16 on which the cargo bed 100 is supported (in addition to the rear frame module 350). In fact, it is contemplated that, in some embodiments, the storage compartment structure 150 may not be used to define the storage compartment 50 at all but rather solely to extend the support structure of the frame 16 on which the cargo bed 100 can be supported.

The right access aperture 52 of the storage compartment 50 is disposed longitudinally between the right vertically-extending frame members 142, 144 and vertically between the right longitudinally-extending frame member 152 and the right longitudinally-extending frame member 254. The right longitudinally-extending frame member 254 extends longitudinally along the bottom right sides of the first and second sections 130, 132 of the front frame module 250. Similarly, the left access aperture 52 of the storage compartment 50 is disposed longitudinally between the left vertically-extending frame members 142, 144 and vertically between the left longitudinally-extending frame member 152 and the left longitudinally-extending frame member 254. The left longitudinally-extending frame member 254 extends longitudinally along the bottom left sides of the first and second sections 130, 132 of the front frame module 250.

With reference to FIGS. 1, 2, 20 and 21, a number of body panels are mounted to the frame 16. These include a hood 164, left and right front fenders 166, left and right side panels 168 and left and right side panels 170. The side panels 168 cover the front vertically-extending frame members 142 and portions of the longitudinally-extending frame members 254 disposed below the access apertures 52 of the storage compartment 50. The side panels 170 cover the rear vertically-extending frame members 144 and part of the motor compartment 60. The right access aperture 52 of the storage compartment 50 is defined at its front and bottom by the right side panel 168, at its rear by the right side panel 170 and at its top by the right longitudinally-extending frame member 152. The left access aperture 52 of the storage compartment 50 is defined at its front and bottom by the left side panel 168, at its rear by the left side panel 170 and at its top by the left longitudinally-extending frame member 152. The side panels 168, 170 also define the structures for receiving the doors 54.

With reference to FIGS. 15 to 18, in this embodiment, a top panel 200 defines a top of the storage compartment 50 and protects the contents thereof. The storage compartment structure 150 extends over the top panel 200. It is contemplated that the top panel 200 could be provided over the storage compartment structure 150. It is also contemplated that the top panel 200 could be omitted. As best seen in FIG. 16, the top panel 200 defines two recesses 202, 204. As can be seen in FIG. 15, part of the engine air intake conduit 74 is received in the recess 202 and part of the CVT air intake conduit 88 is received in the recess 202. More specifically, a laterally extending portion 206 of the recess 202 receives a lower part of the air box 78 and a longitudinally extending portion 208 of the recess 202 receives the section 82 of the pipe 80. The longitudinally extending portion 208 of the recess 202 also receives part of the coolant line 86. As can be seen, the section 82 of the pipe 80 and the coolant line 86 extend under the storage compartment structure 150 so as to be vertically between the storage compartment structure 150 and the top panel 200. The section 82 of the pipe 80 is therefore vertically between the storage compartment 50 and the storage compartment structure 150. The recess 204 receives the section 96 of the pipe 94. As can be seen, the section 96 of the pipe 94 extends under the storage compartment structure 150 so as to be vertically between the storage compartment structure 150 and the top panel 200. The section 96 of the pipe 94 is therefore vertically between the storage compartment 50 and the storage compartment structure 150. It is contemplated that the top panel 200 could be made of multiple parts.

With reference to FIGS. 16 to 19, the vehicle 10 also has a front partition 210, an upper central partition 212, a lower central partition 214, a rear partition 216 and the floor 218. The top panel 200 extends between the upper central partition 212 and the rear partition 216. At its front, the top panel 200 is connected to the rear side of the upper central partition 212. At its rear, the top panel 200 is connected to the frame 16.

The floor 218 is disposed over the lower frame structure 252 of the frame 16 in the first and second sections 130, 132 of the front frame module 250. As such, the floor 218 defines the floor (bottom) of the storage compartment 50 and the floor of the cockpit 22. The storage compartment structure 150 and the portion of the floor 218 defining the floor of the storage compartment 50 (i.e., the storage compartment floor) thus partly define the storage compartment 50 therebetween. The floor 218 also defines a tunnel 220 that receives the tunnel 136 of the frame 16 therein. It is contemplated that the floor 218 could be two separate pieces: one to form the bottom of the storage compartment 50, one to form the floor of the cockpit 22. It is also contemplated that the floor 218 could be made of more than two pieces.

The front partition 210 is disposed in the cockpit 22 at the front of the floor 218 and is connected to the first section 130 of the front frame module 250. The front partition 210 defines the front of the cockpit 22. The front partition 210 also defines part of the wheel wells 222 of the front wheels 12. It is contemplated that the front partition 210 could be made of multiple parts.

The upper central partition 212 is disposed between the cockpit 22 and the storage compartment 50. More specifically, the upper central partition 212 is disposed behind the seats 24, 25, 26. As best seen in FIG. 17, part of the upper central partition 212 extends above the top panel 200 and another part of the upper central partition 212 extends below the top panel 200. The part of the upper central partition 212 that extends above the top panel 200 provides various features for connecting components of the engine air intake conduit 74 and of the CVT air intake conduit 88 to the back of the upper central partition 212. More specifically, as can be seen in FIG. 3, the inlet 76, the air box 78, the inlet 90 and the gooseneck 92 are connected to the back of the upper central partition 212. The upper central partition 212 also defines a bracket 224 for receiving the coolant bottle 84. As can be seen in FIG. 1, when the cargo bed 100 is in the lowered position, the inlet 76, the air box 78, the coolant bottle 84, the inlet 90 and the gooseneck 92 are between the upper central partition 212 and the front wall 104 of the cargo bed 100 so as to be mostly hidden from view. With reference to FIG. 17, the part of the upper central partition 212 that extends below the top panel 200 defines an upper part of the front of the storage compartment 50. It is contemplated that the upper central partition 212 could be made of multiple parts.

With references to FIGS. 16 to 19, the lower central partition 214 is disposed under the seats 24, 25, 26. The lower central partition 214 has a generally horizontal portion that extends forward from a bottom of the upper central partition 212 so as to extend under the seats 24, 25, 26. The lower central partition 214 also has a generally vertical portion that extends downward from a front of the generally horizontal portion of the lower central partition 214 to the floor 218. This generally vertical portion of the lower central partition 214 defines a lower part of the front storage compartment 50. As a result, and as best seen in FIG. 18, a portion of the storage compartment 50 extends and is disposed under the seats 24, 25, 26 and is closer to the front of the vehicle 10 than the doors 54. The sides of the portion of the storage compartment 50 defined under the seats 24, 25, 26 are closed by panels 226. It is contemplated that the lower central partition 214 could be shaped differently such that the storage compartment 50 extends under only one or two of the seats 24, 25, 26 or could not extend under the seats 24, 25, 26. It is contemplated that the lower central partition 214 could be made of multiple parts. It is also contemplated that the upper and lower central partitions 212, 214 could be integrally formed.

The rear partition 216 is disposed between the storage compartment 50 and the motor compartment 60 at the rear end of the floor 218. The rear partition 216 defines part of the rear of the storage compartment 50. The motor 62, the CVT 64, the CVT housing 66, the transaxle 68, the muffler 70 and the fuel tank 72 are disposed rearward of the rear partition 216.

As can be seen in FIGS. 2, 5A, 6, 15 to 17 and 21, the storage space defined by the storage compartment 50 extends continuously from one access aperture 52 to the other access aperture 52. As such, and as can be seen in FIGS. 2 and 21, when the doors 54 are removed, one can see right through the vehicle 10. The storage compartment 50 occupies almost the entire width of the vehicle 10, more specifically the entire width of the vehicle 10 minus the thickness of the doors 54, and is more than half as long as it is wide along the floor 218. This permits a substantial amount of cargo and/or cargo of substantial size to be stored in the storage compartment 50. The top panel 200, the partitions 210, 212, 214, 216 and the floor 218 separate the storage space to separate stored cargo from any other components of the vehicle 10. As such, cargo stored in the storage compartment 50 cannot accidentally damage or be accidentally damaged by other components of the vehicle 10.

As described above, the vehicle 10 is assembled in part by connecting the front and rear frame modules 250, 350 and by adapting the frame 16 with the storage compartment structure 150 (which, given its position along the frame 16, can also be referred to as the upper central frame structure 150) to use the configurable space 275 to implement the storage compartment 50.

As mentioned above, the family of vehicles to which the vehicle 10 belongs also includes the vehicle 510, illustrated in FIGS. 22 to 26. As will be seen below, while the vehicle 510 is assembled by using the same front and rear frame modules 250, 350 that are used to assemble the vehicle 10, the frame of the vehicle 510 is then adapted differently such as to use the configurable space 275 for a different purpose.

The vehicle 510 uses many of the same components as the vehicle 510 and thus like components have been identified with like reference numerals. It will be understood that variants of these components may be used for the vehicle 510 (e.g., a different motor, a different CVT, different seats, different wheels, etc.) instead of the same exact components as in the vehicle 10. The vehicle 510 has a frame 516 to which front and rear suspension assemblies 518, 520 are connected. Front and rear wheels 512, 514 are mounted to the front and rear suspension assemblies 518, 520. The vehicle 510 has a wheelbase length WB_(B) measured longitudinally between the center 513 of the front wheels 512 and the center 515 of the rear wheels 514 (when the wheels 512, 514 are in a straight ahead orientation—i.e., not turning).

The frame 516 of the vehicle 510 is formed in part by connecting the front frame module 250 and the rear frame module 350 which were described above. The motor 562 is disposed in the motor compartment 60 defined by the rear frame module 350. With reference to FIGS. 27A and 27B, the CVT 564, the transaxle 568, the muffler (not shown) and the fuel tank (not shown) are mounted to the rear frame module 350 in the same manner described above with reference to the vehicle 10. As shown in FIG. 27B, the front differential 565 is mounted to the front frame module 250. The vehicle 510 has a front-rear output distance FR_(B) measured longitudinally between a front differential output axis 567 of the front differential 565 and a transaxle output axis 569 of the transaxle 568 (i.e., the distance between the frontmost output axis and the rearmost output axis).

In contrast with the frame 16 of the vehicle 10, the frame 516 of the vehicle 510 is not provided with the storage compartment structure 150. Rather, the configurable space 275 defined by the front frame module 250 is used as an additional seat row space in order to install another seat row RSR disposed rearward of the seat row FSR. As such, the seat row FSR may be referred to as a “front seat row” and the seat row RSR may be referred to as a “rear seat row”. In this embodiment, the rear seat row RSR includes a left rear seat 624, a right rear seat 626, and a center rear seat 625 disposed between the seats 624, 626. Thus, in the vehicle 510, the configurable space 275 is part of the cockpit 522 such that the cockpit 522 extends along a greater length of the vehicle 510 compared to the vehicle 10.

In order to protect passengers seated in the rear seat row RSR, a different roll cage amongst the family of roll cages is installed on the vehicle 510. Notably, a roll cage 528 is connected to the frame 516 to extend over the front seat row FSR and the rear seat row RSR. The roll cage 528 has a length that is greater than a length of the roll cage 28 of the vehicle 10. The roll cage 528 may thus be referred to as “long roll cage” and the roll cage 28 may be referred to as a “short roll cage”. The long roll cage 528 has many of the same components used in the short roll cage 28. For instance, the long roll cage 528 has the same front legs 138 and rear legs 140 as the short roll cage 28. FIG. 29 shows the front frame module 250 mounted with components of the long roll cage 528 that extend over the front seat row space 265 (and thus the front seat row FSR). The front legs 138 are connected to the roll cage mounts 139 in the same manner as described above with respect to the vehicle 10. However, instead of the rear legs 140 being connected to the roll cage mounts 143, intermediate legs 165 are connected to the roll cage mounts 143 for supporting the roll cage 528 longitudinally between the front and rear legs 138, 140. The rear legs 140 are connected to the rear vertically-extending frame members 144. More specifically, lower connectors 169 of the rear legs 140 are connected to the mounts 147 defined at the top ends of the rear vertically-extending frame members 144. The mounts 147 may thus be referred to as “roll cage mounts”. The roll cage mounts 147 can thus be used to connect the rear legs 140 or to connect the storage compartment structure 150. As shown in FIGS. 30 and 31, each of the rear legs 140 is connected, via a roll cage connector 161, to a corresponding longitudinally-extending roll cage member 162. The front legs 138, the intermediate legs 165 and the longitudinally-extending roll cage members 162 are connected at front roll cage connectors 163 (FIG. 29). Notably the longitudinally-extending roll cage members 162 have connecting end portions 167 for connecting to the front roll cage connectors 163. As such, the front legs 138, rear legs 140 and intermediate legs 165 are all connected to one another to form the roll cage 528. A laterally-extending roll cage member 175 extends between the laterally opposite connectors 163.

As shown in FIG. 27A, a CVT air intake conduit 588 is provided to supply air inside the CVT housing 566 to cool the CVT 564. The CVT air intake conduit 588 includes an inlet 590 in fluid communication with the CVT housing 566 via a gooseneck and a pipe (not shown—similar to the gooseneck 92 and pipe 94 of the vehicle 10). The inlet 590 is disposed on a left side of the vehicle 510, rearward of the left rear passenger seat 624 of the rear seat row RSR. The air intake aperture defined by the inlet 590 faces leftward.

An engine air intake conduit (not shown) is also provided for supplying air to the motor 562. The engine air intake conduit is similar to the engine air intake conduit 74 of the vehicle 10 except that, similarly to the CVT air intake conduit 588, the inlet of the engine air intake conduit of the vehicle 510 is disposed rearward of the rear seat row RSR, specifically the right rear passenger seat 626.

Since the cockpit 522 is longer than the cockpit of the vehicle 10 due to the rear seat row RSR, the vehicle 510 does not have the space required for installing the long cargo bed 100. Instead, the vehicle 510 is equipped with the short cargo bed 300. The short cargo bed 300 is similar in many aspects to the long cargo bed 100 except that the length L_(S) (FIG. 23) of the short cargo bed 300 is less than the length L_(L) of the long cargo bed 100. The short cargo bed 300 has a floor 302, a front wall 304, left and right side walls 306 and a tailgate 308. It is contemplated that one or more of the front wall 304, the left and right side walls 306 and the tailgate 308 could be selectively removable. It is also contemplated that one or more of the front wall 304, the left and right side walls 306 and the tailgate 308 could be omitted. It is also contemplated that the tailgate 308 could be replaced by a rear wall, which could be selectively removable. It is also contemplated that the short cargo bed 300 could have a movable or removable top. Brackets 310 are connected to the bottom of the short cargo bed 300 near a rear thereof and pivotally connect the short cargo bed 300 to the rear frame module 350. Notably, the short cargo bed 300 is pivotally mounted to the cargo bed pivot 371 defined by the axles 370. As such, similarly to the long cargo bed 100, the short cargo bed 300 can pivot about the cargo bed pivot axis 380 between a lowered position and a raised position. As best seen in FIG. 23, when the short cargo bed 300 is in the lowered position, the short cargo bed 300 extends over the motor compartment 60 but not over the configurable space 275. Moreover, the short cargo bed 300 is disposed rearwardly of the roll cage mounts 147 (both in the lowered and raised positions). A lock 312 (FIG. 27C) similar to that described with respect to the long cargo bed 100 is provided to lock the short cargo bed 300 in place in the lowered position. Notably, the lock 312 includes a pair of spring-biased hooks 314 and a release handle 316. Instead of engaging the storage compartment structure 150 for locking, the hooks 314 of the lock 312 engage the laterally-extending retaining members 355 of the rear frame module 350. Thus, the distance between the hooks 314 and the cargo bed pivot axis 380 is approximately the same as the distance between the laterally-extending retaining members 355 and the cargo bed pivot axis 380. To pivot the short cargo bed 300 to the raised position, a user first actuates a release handle (not shown) thereby causing a hook of the locking system to release the member of the rear frame module 350. The short cargo bed 300 can then be pivoted to the raised position. A gas cylinder (not shown) connected between the frame 516 and the bottom of the cargo bed 300 helps to maintain the cargo bed 300 in the raised position. In the present embodiment, the cargo bed 300 is pivoted manually between its lowered and raised positions, but it is contemplated that it could be pivoted by an actuator such as an electric or hydraulic actuator.

The vehicle 510 is assembled, similarly to the vehicle 10, in part by connecting the front frame module 250 and the rear frame module 350. However, instead of using the configurable space 275 for the storage compartment 50 and to extend the space available for the cargo bed, in the vehicle 510 the configurable space 275 is used as a seat row space 285 to accommodate the rear seat row RSR. Consequently, the vehicle 510 is equipped with the short cargo bed 300 instead of the long cargo bed 100. Despite these functional differences, the wheelbase length WB_(B) of the vehicle 510 is approximately the same as the wheelbase length WB_(A) of the vehicle 10. That is, the difference between the wheelbase lengths WB_(A), WB_(B) is solely due to manufacturing tolerances (i.e., ±0.1%). Similarly, a longitudinal cargo pivot distance PV_(B) of the vehicle 510 measured between the center 513 of the front wheels 512 and the cargo bed pivot axis 380 (when the front wheels 12 are in a straight ahead orientation—i.e., not turning) is approximately the same as the longitudinal pivot distance PV_(A) of the vehicle 10. That is, the difference between the longitudinal pivot distances PV_(A), PV_(B) is solely due to manufacturing tolerances (i.e., ±0.1%). Similarly, the front-rear output distance FR_(B) of the vehicle 510 is approximately the same as the front-rear output distance FR_(A) of the vehicle 10. That is, the difference between the front-rear output distances FR_(A), FR_(B) is solely due to manufacturing tolerances (i.e., ±0.1%).

Given the longer cockpit 522, the vehicle 510 may have different and/or additional partitions than those described with reference to the vehicle 10. Moreover, in the vehicle 510, the portion of the floor 218 extending between the front and rear vertically-extending frame members 142, 144 now acts as a cockpit floor (rather than as storage compartment floor). The vehicle 510 also has body panels, including a hood 664, left and right front fenders 666, left and right side panels 668 and left and right side panels 670. In this embodiment, the hood 664, front fenders 666 and side panels 668, 670 are the same as those used for the vehicle 10 (the hood 164, the front fenders 166, and the side panels 168, 170). It is contemplated that, in other embodiments, the body panels of the vehicle 510 could be different from those used for the vehicle 10.

In some embodiments, the front frame module 250 used to assemble the vehicles 10, 510 may be subdivided in sub-modules that are connected to one another. For instance, as shown in FIG. 32, in some embodiments, the front frame module 250 has a front sub-module 250 _(F) and a central sub-module 250 _(C) connected to and disposed rearward of the front sub-module 250 _(F). The front sub-module 250 _(F) includes the first section 130 while the central sub-module 250 _(C) includes the second section 132. Thus, the front sub-module 250 _(F) includes the front suspension mounting structure 264 and the front vertically-extending frame members 142, while the central sub-module 250 _(C) includes the rear vertically-extending frame members 144 and defines the configurable space 275. In this embodiment, the longitudinally-extending frame members 254 of the lower frame structure 252 include front longitudinally-extending frame members 254 _(F) and central longitudinally-extending frame members 254 _(C) which are connected to one another when the front and central sub-modules 250 _(F), 250 _(C) are connected. Similarly, the longitudinally-extending frame members 255 of the lower frame structure 252 include front and central longitudinally-extending frame members (not shown) which are connected to one another. The tunnel 136 is subdivided in two pieces 136F, 136 _(C) which are connected to one another. In such an embodiment, when the vehicle 510 is assembled, the rear seat row RSR is thus installed within the configurable space 275 defined by the central sub-module 250 _(C). Moreover, when the vehicle 10 is assembled, the long cargo bed 100 extends longitudinally, in the lowered position, over the configurable space 275 (e.g., at least a rear portion thereof) defined by the central sub-module 250 _(C).

It is to be understood that the present technology does not imply any particular construction of the frame modules of the vehicles. That is, the specific construction of the modules of the frame 16 of the vehicle 10 and the frame 516 of the vehicle 510 may be configured in other ways in other embodiments. Rather, the present technology provides that the frame of each vehicle of the family of vehicles shares common frame modules with the frame of other vehicles of the family.

The vehicle 710 will now be described with reference to FIGS. 33 to 37C. The vehicle 710 uses many of the same components as the vehicle 10 and thus like components have been identified with like reference numerals. It will be understood that variants of these components may be used for the vehicle 710 (e.g., a different motor, a different CVT, different seats, different wheels, etc.) instead of the same exact components as in the vehicle 10.

As shown in FIGS. 34 to 36, the vehicle 710 has a frame 716 to which left and right front suspension assemblies 718, left and right rear suspension assemblies 720, and left and right additional rear suspension assemblies 723 are connected. Left and right front wheels 712 are mounted to the front suspension assemblies 718, left and right rear wheels 714 are mounted to the rear suspension assemblies 720, and left and right additional rear wheels 729 are mounted to the additional rear suspension assemblies 723. The vehicle 710 is a six-wheeled vehicle including dual rear axles (i.e., having two sets of rear wheels) which may provide additional traction when driving the vehicle 710. As shown in FIG. 34, the vehicle 710 has a wheelbase length WB_(C) measured longitudinally between the center 713 of the front wheels 712 and the center 731 of the additional rear wheels 729 (when the wheels 712, 714, 729 are in a straight ahead orientation—i.e., not turning).

As shown in FIG. 34, the frame 716 of the vehicle 710 is assembled by using the same rear frame module 350 that is used to assemble the vehicles 10, 510. However, other frame modules 850, 950 are also connected to the rear frame module 350 to assemble the vehicle 710. Notably, an alternative front frame module 850 (FIG. 38) defining a cockpit 722 of the vehicle 710 and an additional rear frame module 950 (FIG. 41) are connected to the rear frame module 350 in order to form the frame 716 of the vehicle 710. The additional rear frame module 950 is rearward of the rear frame module 350. Thus, the rear frame module 350 may alternatively be referred to as a “central” frame module in the context of the vehicle 710 (and the suspension assemblies 720 and wheels 714 can be referred to as central suspension assemblies 720 and central wheels 714).

As shown in FIGS. 38 to 40, the alternative front frame module 850 is similar to the first section 130 of the front frame module 250 described above and thus similar to the sub-module 250 _(F). Therefore, like components to that of the front frame module 250 have been identified with like reference numerals and will not be described here again. The recess 245 (FIGS. 38, 39) defined in each of the vertically-extending frame members 142 is configured for receiving therein the upper laterally-extending frame member 360 of the rear frame module 350. As such, when the frame 716 is assembled, the vertically-extending frame members 142 of the alternative front frame module 850 are supported by the vertical members 358 of the rear frame module 350 which are connected to the upper laterally-extending frame member 360. To connect the alternative front frame module 850 to the rear frame module 350, the vertical members 358 are fastened to the vertically-extending frame members 142.

As shown in FIG. 37B, a front differential 765 is mounted to the alternative front frame module 850. The front differential 765 has a front differential output axis 767 about which the half-shafts connected thereto rotate.

The roll cage 28 is connected to the alternative front frame module 850 to extend over the seat row FSR. In this embodiment, the roll cage 28 is the same short roll cage as that used for the vehicle 10, notably including the front and rear legs 138, 140. The front legs 138 are connected at a front of the cockpit 722 to the left and right roll cage mounts 139 defined at the ends of the laterally-extending upper frame member 262. The rear legs 140 are connected at a rear of the cockpit 722 to left and right roll cage mounts 143 defined at the top ends of the vertically-extending frame members 142 (located longitudinally rearward of the roll cage mounts 139). The roll cage mounts 143 include a plurality of openings extending laterally across the vertically-extending frame members 142. The front and rear legs 138, 140 are connected to one another via the connectors 149 which are connected to one of each of the front and rear legs 138, 140.

The additional rear frame module 950 is shown in FIGS. 41 to 43. The additional rear frame module 950 has lower longitudinally-extending frame members 952 and upper longitudinally-extending frame members 954. An upper laterally-extending frame member 957 extends between the frame members 954 near their front ends. Frontwardly and upwardly extending members 956 extend between the lower longitudinally-extending frame members 952 and the upper laterally-extending frame member 957. At their rear ends, the frame members 954 are connected to one another by an upper laterally-extending frame member 958. The longitudinally-extending frame members 954 have connecting portions 964 at their front ends. The connecting portions 964 are affixed to a rear top portion of the rear frame module 350 via permanent fasteners (not shown) such as, for example Hemlok® fasteners by Avdel, extending through openings 977 defined by the connecting portions 964. Each connecting portion 964 has a recess 965 for engaging a corresponding axle 370 of the rear frame module 350. In this embodiment, each of the recesses 965 forms a hook for engaging the corresponding axles 370. The recesses 965 define a central axis 975 that extends laterally through a center of each of the recesses 965. Moreover, the upper laterally-extending frame member 957 has fasteners 959 protruding forwardly therefrom to connect with the rear laterally-extending frame member 364 of the rear frame module 350. A front lower laterally-extending member 966 and a bottom connecting plate 961 extending forwardly therefrom are also configured to be connected to a rear bottom portion of the rear frame module 350 via fasteners 977 extending vertically. In this embodiment, the fasteners 977 are permanent fasteners such as, for example HuckBolts® by Arconic (e.g., Magna-Grip MGPB-E12-14). In addition, fasteners 973 extending forwardly from the front lower laterally-extending member 966 are also connected to the rear bottom portion of the rear frame module 350. The fasteners 959, 973 may be removable or permanent fasteners. In yet other embodiments, the fasteners 959, 973 may include a mix of removable and permanent fasteners.

The additional rear frame module 950 also has an additional rear suspension mounting structure 960 for connecting the additional rear suspension assemblies 723 to the frame 716. The rear suspension mounting structure 960 includes two inverted Y-shaped mounts 962 disposed laterally opposite from one another. The inverted Y-shaped mounts 962 are connected at a lower end thereof to the lower longitudinally-extending members 952 (via connecting members 963) and, at an upper end thereof, to the upper longitudinally-extending members 954. A rear bottom mounting plate 972 extends between the inverted Y-shaped mounts 962. Two upper mounting flanges 974 extend inwardly form the inverted Y-shaped mounts 962. A front bottom plate 967 extends between the lower longitudinally-extending members 952. A rear differential 775 (FIG. 37B) is connected to and supported by the additional rear frame module 950 of the frame 716 via one or more of the front and rear bottom plates 967, 972 and the flanges 974 or other structures of the additional rear frame module 950. The rear differential 775 is operatively connected to the transaxle 768. The rear differential 775 is connected by half-shafts (not shown) to the two additional rear wheels 729 to drive the two additional rear wheels 729. As shown in FIG. 37B, the rear differential 775 has a rear differential output axis 777 about which the half-shafts connected thereto rotate. The vehicle 710 has a front-rear output distance FR_(C) measured longitudinally between the front differential output axis 767 and the rear differential output axis 777 (i.e., the distance between the frontmost output axis and the rearmost output axis).

At its top portion, the additional rear frame module 950 has a cargo bed support structure 968 for supporting the long cargo bed 100. More specifically, the cargo bed support structure 968 includes left and right corner members 969 connected to the ends of the rear laterally-extending frame member 958. Each of the corner members 969 has an axle 970 extending laterally outwardly therefrom. The axles 970 are coaxial with one another. Together, the axles 970 define in part a cargo bed pivot 971 for pivotably mounting the long cargo bed 100 to the additional rear frame module 950. As such, the long cargo bed 100 is pivotable about a cargo bed pivot axis 980 (FIGS. 42, 43) defined by the cargo bed pivot 971. More specifically, the brackets 110 connected to the bottom of the cargo bed 100 are pivotally connected to the cargo bed pivot 971 to allow the long cargo bed 100 to pivot about the cargo bed pivot axis 980. As shown in FIG. 34, the vehicle 10 has a longitudinal cargo pivot distance PV_(C) measured between the center 713 of the front wheels 712 and the cargo bed pivot axis 980 (when the front wheels 712 are in a straight ahead orientation—i.e., not turning).

Furthermore, a distance L_(RM) (as seen in FIG. 43) measured longitudinally between the central axis 975 of the recesses 965 and the cargo bed pivot axis 980 can be defined as a length of the additional rear frame module 950. As shown in FIG. 37B, the length L_(RM) of the additional rear frame module 950 corresponds to a distance RR measured longitudinally between the transaxle output axis 769 of the transaxle 768 and the rear differential output axis 777 of the rear differential 775. That is, the length Lit is approximately equal to the distance RR. Furthermore, length L_(RM) and the distance RR are approximately equal to a distance WB_(C2) between the centers 715, 731 of the central wheels 714 and the additional rear wheels 729. As such, a difference between the wheelbase length WB_(C) and the length L_(RM) of the additional rear frame module 950 is equal to a distance WB_(C1) between the centers 713, 715 of the front wheels 712 and the central wheels 714.

As briefly mentioned above and as shown in FIG. 37C, in the context of the vehicle 710, the laterally-extending retaining members 355 of the rear frame module 350 are used for retaining the cargo bed 100 in its lowered position. Notably, in the lowered position of the cargo bed 100, the hooks 114 of the lock 112 engage a respective one of the laterally-extending retaining members 355 to keep the cargo bed 100 in the lowered position. To that end, a distance between the laterally-extending retaining members 355 and the cargo bed pivot axis 980 in the vehicle 710 is approximately the same as a distance between the laterally-extending frame member 118 and the cargo bed pivot axis 380 in the vehicle 10 as the positioning of the lock 112 on the cargo bed 100 is the same in both vehicles.

The assembled frame 716 is shown in FIG. 47. As shown, the frame 716 defines the seat row space 265 in the alternative front frame module 850. The motor compartment 760 of the vehicle 710, defined by the rear frame module 350, is disposed rearwardly of the cockpit 22 and frontwardly of the additional rear frame module 950. The two rear suspension mounting structures 362, 962 are disposed rearwardly of the cockpit 722. In the context of the vehicle 710, the rear frame module 350 can also be considered as a “cargo bed support structure extension” (similarly to the storage compartment structure 150 described above) in that it extends the structure of the frame 716 on which the cargo bed 100 is supported.

As shown in FIG. 34, a CVT air intake conduit 788 is provided to supply air inside the CVT housing to cool the CVT 764 (shown schematically in FIG. 34). The CVT air intake conduit 788 includes an inlet 790 in fluid communication with the CVT housing via a gooseneck and a pipe (not shown—similar to the gooseneck 92 and pipe 94 of the vehicle 10). The inlet 790 is disposed on a left side of the vehicle 710, rearward of the cockpit 722, and extending above the rear frame module 350. The air intake aperture defined by the inlet 790 faces leftward.

An engine air intake conduit (not shown) is also provided for supplying air to the motor 762 (shown schematically in FIG. 34). The engine air intake conduit is similar to the engine air intake conduit 74 of the vehicle 10 except that, similarly to the CVT air intake conduit 788, the inlet of the engine air intake conduit of the vehicle is located rearward of the cockpit 722 and extends above the rear frame module 350.

The vehicle 710 may have different and/or additional partitions than those described with reference to the vehicle 10 and the vehicle 510. Moreover, in the vehicle 710, the floor 218 extends between the frame members 142, 260 since there is no longer cockpit or a storage compartment to accommodate. The vehicle 710 also has body panels, including a hood 764, left and right front fenders 766, and left and right side panels 768. In this embodiment, the hood 764, front fenders 766 and side panels 768 are the same as those used for the vehicle 10 and the vehicle 510 (the hood 164, the front fenders 166, the side panels 168). It is contemplated that, in other embodiments, the body panels of the vehicle 710 could be different from those used for the vehicles 10, 510.

Despite the functional differences between the vehicles 10, 510, 710, the wheelbase lengths WB_(A), WB_(B), WB_(C) of the vehicles 10, 510, 710 are all approximately the same. That is, the differences between the wheelbase lengths WB_(A), WB_(B), WB_(C) are solely due to manufacturing tolerances (i.e., ±0.1%). In other words, the wheelbase lengths of the vehicles are approximately the same regardless of which of the rear seat row RSR or a cargo bed support structure extension is disposed rearwardly of the seat row FSR. Similarly, the longitudinal cargo pivot distances PV_(A), PV_(B), PV_(C) of the vehicles 10, 510, 710 are all approximately the same. That is, the differences between the longitudinal cargo pivot distances PV_(A), PV_(B), PV_(C) are solely due to manufacturing tolerances (i.e., ±0.1%). In other words, the longitudinal cargo pivot distances of the vehicles are approximately the same regardless of which of the rear seat row RSR or a cargo bed support structure extension is disposed rearwardly of the seat row FSR. Similarly, the front-rear output distances FR_(A), FR_(B), FR_(C) of the vehicles 10, 510, 710 are all approximately the same. That is, the differences between the front-rear output distances FR_(A), FR_(B), FR_(C) are solely due to manufacturing tolerances (i.e., ±0.1%). In other words, the front-rear output distances of the vehicles are approximately the same regardless of which of the rear seat row RSR or a cargo bed support structure extension is disposed rearwardly of the seat row FSR.

The common wheelbase lengths WB_(A), WB_(B), WB_(C), longitudinal cargo pivot distances PV_(A), PV_(B), PV_(C), and front-rear output distances FR_(A), FR_(B), FR_(C) of the vehicles 10, 510, 710 allow avoiding a substantial redesign of the frames 16, 516, 716. Notably, if one or both of these dimensions were to vary substantially across the vehicles 10, 510, 710, the corresponding frame 16, 516, 716 would have to be redesigned to ensure it can support the load exerted thereon by the various vehicle components. Furthermore, by keeping these dimensions constant throughout the vehicles 10, 510, 710, certain components that are common to each of the vehicles 10, 510, 710 are ensured to fit the vehicles 10, 510, 710, thus avoiding designing different components with different dimensions for each of the vehicles 10, 510, 710. In turn, this may reduce the manufacturing complexity of the vehicles 10, 510, 710 while reducing their associated production costs.

Furthermore, as can be seen in FIG. 50, the configuration of the structure of the frames 16, 516, 716 to which the hooks 114, 314 of the locks 112, 312 latch onto when the cargo beds 100, 300 are in the lowered position is substantially similar in each of the frames 16, 516, 716. As described above, in the context of the frame 16 of the vehicle 10, the hooks 114 of the lock 112 latch onto the laterally-extending frame member 118 of the storage compartment structure 150 when the cargo bed 100 is in the lowered position. On the other hand, in the context of the frames 516, 716 of the vehicles 510, 710, the hooks 114, 314 of the locks 112, 312 of the cargo beds 100, 300 (the cargo bed 100 for the vehicle 710, and the cargo bed 300 for the vehicle 510) latch onto the laterally-extending retaining members 355. However, in each of the frames 16, 516, 716, the geometry of the lock-engaging frame subassemblies 119, 357 which support the hooks 114, 314 is substantially similar, notably including, for each hook 114, 314, a laterally-extending member (laterally-extending frame member 118 or laterally-extending retaining member 355) and a supporting member (diagonal frame member 156 or longitudinally-extending frame member 354) connected to the laterally-extending member and disposed at a specific angle relative thereto. In particular, as described above, the angle α between the laterally-extending frame member 118 and each diagonal frame member 156 is equal to the angle θ between each laterally-extending retaining member 355 and a respective longitudinally-extending frame member 354. Given this similar geometry and constant angular disposition between these frame members throughout the frames 16, 516, 716, the cargo beds 100, 300 can be more easily installed on any given one of the frames 16, 516, 716 without needing further customization since the supporting structure is substantially similar in each case.

This similarity between the geometry of the supporting structure of the frame onto which the hooks 114, 314 of the locks 112, 312 latch onto in the lowered position can also extend to other vehicles which are made from two or more of the frame modules 250, 350, 850, 950. For instance, a vehicle 1010, partially illustrated in FIGS. 51 and 52, is assembled by connecting the alternative front frame module 850 and the rear frame module 350 to one another to form a frame 1016 of the vehicle 1010. The vehicle 1010 is a four-wheeled vehicle with wheelbase that is smaller than the wheelbase lengths WB_(A), WB_(B), WB_(C) of the vehicles 10, 510, 710. As shown in FIG. 51, the vehicle 1010 is equipped with the short cargo bed 300 which, through the hooks 314 of its lock 312, latches onto the laterally-extending retaining members 355 of the rear frame module 350. Furthermore, as shown in FIG. 52, as described above with respect to the frames 16, 516, 716 of the vehicles 10, 510, 710, the configuration of the structure of the frame 1016 to which the hooks 314 of the lock 312 latch onto when the cargo bed 300 is in the lowered position is substantially similar to that of the frames 16, 516, 716. Notably, the geometry of the lock-engaging frame subassembly 357 which support the hooks 314 in the vehicle 1010 is substantially similar as that in the vehicles 10, 510, 710, notably including, for each hook 314, a laterally-extending retaining member 355 and a longitudinally-extending frame member 354 connected thereto and disposed at the angle θ (which is equal to the angle α) relative thereto.

It is contemplated that, in some embodiments, both the front frame module 250 and the alternative front frame module 850 may include part of the roll cage 28. For instance, as shown in FIGS. 48 and 49, each of a front frame module 250* and an alternative front frame module 850* could incorporate the front legs 138 and the rear legs 140 of the roll cage 28. The front frame module 250* and the alternative front frame module 850* could be used to assemble the respective frames 16, 716 of the vehicles 10, 710.

In such an embodiment, the distinction between the front frame module 250* and the alternative front frame module 850* is a lower portion thereof. Notably, the front frame module 250* has a top portion TP1 that is identical to a top portion TP2 of the alternative front frame module 850*. In this embodiment, the top portions TP1, TP2 include the front and rear legs 138, 140, the front upper lateral member 145, the rear upper lateral member 155 and the connectors 149. In some embodiments, the top portions TP1, TP2 may not include the rear legs 140.

On the other hand, the front frame module 250* has a base portion BP1 that is different from a base portion BP2 of the alternative front frame module 850*. In particular, the base portion BP1 has a length that is greater than a length of the base portion BP2. The base portions BP1, BP2 are connected to the respective top portions TP1, TP2 (via the roll cage mounts described above). The base portion BP1 includes the lower frame structure 252 of the front frame module 250*, as well as the vertically-extending frame members 142, 144, 260, the front suspension mounting structure 264 and the bumper structure 270. The base portion BP2 includes the lower frame structure 252 of the alternative front frame module 850*, as well as the vertically-extending frame members 142, 260, the front suspension mounting structure 264 and the bumper structure 270. Thus, in other words, the underlying structures of the base portions BP1, BP2 are identical from the respective front suspension mounting structures 264 to the vertically-extending frame members 142. Minor differences may exist between certain components of the base portions BP1, BP2. For instance, as shown in FIG. 49, the bumper structure 270 of the alternative front frame module 850* is different from the bumper structure 270 of the front frame module 250*.

As such, the lower frame structure 252 of the front frame module 250* extends rearwardly of the rear legs 140. In contrast, the rear legs 140 of the alternative front frame module 850* extend rearwardly of the lower frame structure 252 of the alternative front frame module 850*.

Modifications and improvements to the above-described embodiments of the present technology may become apparent to those skilled in the art. The foregoing description is intended to be exemplary rather than limiting. The scope of the present technology is therefore intended to be limited solely by the scope of the appended claims.
